Psycholinguistic research has shown that the influence of abstract syntactic knowledge on performance is shaped by particular sentences that have been experienced. To explore this idea, the authors applied a connectionist model of sentence production to the development and use of abstract syntax. The model makes use of (a) error-based learning to…

Contemporary civilization has created a fundamental contradiction between the intellectual approach to knowing and the technical approach to doing on the one hand, and the results of their application on the other. These approaches to knowing and doing begin with a process of abstraction that trades breadth for depth, while their application…

Abstraction is a major concept in computer science and serves as a powerful tool in software development. Pattern-oriented instruction (POI) is a pedagogical approach that incorporates patterns in an introductory computer science course in order to structure the learning of algorithmic problem solving. This paper examines abstraction processes in…

This paper describes the development, use, and analysis, of an educational tool inspired by the history of the optical mechanism of vision. We investigated 12-year-old students' reasoning about vision. Most of them explain it as the result of something coming either from the object or from the eye. Moreover, some of them think that light…

This article describes how first graders' sense of number can be developed through the perspective of measurement. (Contains 5 figures.)

Students' views about science were correlated with their approaches to lab practice. Three distinct cases are discussed in detail: empiricist-oriented, rationalist-oriented, and constructivist-oriented students. A coherent epistemological theory was constructed for each case, by considering the different degrees of certainty and confidence each…

Most students in America can graduate from high school without ever analyzing a piece of art. Perhaps these students will take an art history or an art appreciation course in college that may incorporate a few references to literature and history. Math or science connections will most likely remain entirely absent. Why do we treat art analysis…

"How ScienceWorks" is now the focus of the national science specifications in English schools. This article is a brief introduction to the philosophy of science from the Greeks to the present day that underpins this notion. It consists of a brief summary of the contributions of nine philosophers and/or scientists to the debate: Aristotle, Roger…

This paper is structured in two sections. The first examines views of mathematical abstraction in two broad categories: empiricist and dialectical accounts. It documents the difficulties involved in and explores the potentialities of both accounts. Then it outlines a recent model which takes a dialectical materialist approach to abstraction in…

The question of what students gain by engaging in socioscientific inquiry is addressed in two ways. First, relevant literature is surveyed to build the case that socioscientific issues (SSI) can serve as useful contexts for teaching and learning science content. Studies are reviewed which document student gains in discipline specific content…

Discusses three motives for and approaches to question-asking, and concludes that the approaches augment and complement each other by accentuating different aspects of the speech communication process. (MH)

This study indicated that the school performance and intelligence quotients of associative responders diverge significantly over time from those of nonassociative responders. This divergence becomes greater with age, suggesting that reliance on associative responding in preference to reasoning may cumulatively interfere with intellectual…

Outlines the logical empiricist philosophy and notes its influence on communication research. Suggests conceptual analysis and programmatic research as focuses for communication theorists. (MH)

Contemporary dispute among teachers of rhetoric between those who prefer the classical tradition of rhetoric and those who champion an epistemic view of rhetoric has antecedents among the disputes of the ancient Greek scholars. Some of the vital themes of epistemology can be traced back to Protagoras of Abdera, one of the two great leaders of the…

This paper presents two puzzles that have emerged in a series of completed and ongoing studies at Queen's University, Ontario. These puzzles concern teachers' professional knowledge, a term used to refer to the non-propositional forms of knowledge assumed to be of importance to professional action. This research assumed that the professional…
